The International Sommelier Guild is an international credentialing authority in sommelier, wine, beverage, hospitality, and wine business education. Established in 1982, ISG provides a structured certification pathway designed to support students, hospitality professionals, wine trade professionals, educators, and serious learners through progressive levels of professional education.
From its North American origins, ISG has developed into an international education provider delivering standardized programs across multiple regions and languages. ISG's academic model is built around a consistent curriculum, structured learning materials, formal assessment, and a defined educational pathway.
ISG is a global network of educators, sommeliers, wine professionals, hospitality specialists, and industry practitioners committed to structured professional education. ISG instructors bring practical experience from restaurants, hotels, wine production, distribution, retail, consulting, and education into both online and classroom learning environments.
ISG provides progressive certification programs in wine, sommelier studies, beverage knowledge, hospitality, wine business, and educator development. The curriculum is designed to move students from foundational wine knowledge to advanced professional study, integrating theory, tasting, service, business context, and applied hospitality skills.
Across the ISG pathway, students may study wine, spirits, beer, sake, service, sensory evaluation, hospitality operations, beverage management, wine trade, enology, nutrition, and leadership, where appropriate to the program level.
ISG delivers education through online, live online, classroom, and hybrid formats. Programs are supported by ISG-developed learning materials, structured lectures, guided tasting, examinations, and academic standards designed to maintain consistency across delivery formats and regions.
ISG's programs are designed as complete, integrated courses, with the required curriculum, learning materials, assessments, and academic expectations aligned within one educational framework. Unlike fragmented course models that separate essential subjects into additional paid courses or require students to purchase outside study materials, ISG includes the required educational materials within the program structure. This provides students with a clearer academic pathway, stronger curriculum alignment, and greater cost transparency from the beginning of their studies.
ISG's educational philosophy is based on structured progression, academic consistency, professional relevance, and student success. ISG believes that rigorous education should be supported by clear expectations, complete learning materials, academic guidance, and fair assessment.
We believe professional education should provide committed students with the structure, guidance, knowledge, confidence, and practical competence needed to succeed within a serious academic framework. ISG measures educational quality through structured learning, academic support, fair assessment, and strong student outcomes — not through unnecessary barriers. ISG takes pride in building an academic structure that supports student success while maintaining high academic standards.
ISG's academic standards are guided by its leadership and independent Board of Education, supporting curriculum consistency, assessment integrity, and professional relevance across the certification pathway.
